Unify input device hotplugging support for embedded
On embedded the mouse cursor will now appear and reappear regardless of how the input handling code is loaded (via a generic plugin or compiled-in to the platform plugin). Instead of passing around QDeviceDiscovery instances that only works when compiling-in the code into the platform plugin, introduce a new internal central QInputDeviceManager. The single instance of this provides a place to store any future input device related signals and properties. Also introduce mouse hotplugging support to linuxfb. [ChangeLog][QtGui] The mouse cursor on Embedded Linux is now handling hotplugging correctly with eglfs and linuxfb regardless of how the input handling code is loaded (via a generic plugin or built in to the platform plugin).
